[Geotools-devel] Determining axis order of a CRS

[Andrea A. <aa...@op...>]

Hi Martin,
I'm trying to solve the following problem. I have a CRS object,
and I need to go back to its id, but this time with a twist,
in that I need to generate a code like "epsg:4326" if the CRS
is lon/lat ordered, and like "urn:x-ogc:def:crs:EPSG:6.11.2:4326"
if the axis order is the opposite (if the system is not geographic
I don't really care, both epsg:x and urn:x are good).

What's the best way to spot the axis order of a crs? I thought
about looking at the name of the first axis in the coordinate
system, yet it seems to be error prone... can I assume the
axis names or a geographic crs are always Lat and Lon?

Cheers
Andrea
